Human Gene CLEC4A (uc001qtz.1) Description and Page Index
  Description: Homo sapiens C-type lectin domain family 4, member A (CLEC4A), transcript variant 1, mRNA.
RefSeq Summary (NM_016184): This gene encodes a member of the C-type lectin/C-type lectin-like domain (CTL/CTLD) superfamily. Members of this family share a common protein fold and have diverse functions, such as cell adhesion, cell-cell signalling, glycoprotein turnover, and roles in inflammation and immune response. The encoded type 2 transmembrane protein may play a role in inflammatory and immune response. Multiple transcript variants encoding distinct isoforms have been identified for this gene. This gene is closely linked to other CTL/CTLD superfamily members on chromosome 12p13 in the natural killer gene complex region. [provided by RefSeq, Jul 2008].

DESCRIPTION: RecName: Full=C-type lectin domain family 4 member A; AltName: Full=C-type lectin DDB27; AltName: Full=C-type lectin superfamily member 6; AltName: Full=Dendritic cell immunoreceptor; AltName: Full=Lectin-like immunoreceptor;
FUNCTION: May be involved in regulating immune reactivity. May play a role in modulating dendritic cells (DC) differentiation and/or maturation. May be involved via its ITIM motif (immunoreceptor tyrosine-based inhibitory motifs) in the inhibition of B-cell-receptor-mediated calcium mobilization and protein tyrosine phosphorylation.
SUBUNIT: May interact with PTPN6 via its ITIM motif.
SUBCELLULAR LOCATION: Membrane; Single-pass type II membrane protein (Probable).
TISSUE SPECIFICITY: Expressed in dendritic cells, myeloid cells, B-cells and HL-60 cells (at protein level). TNF alpha, IL-1 alpha, and LPS, down-regulated expression at the surface of neutrophils (at protein level). Expressed preferentially in hematopoietic tissues. Expressed in peripheral blood leukocytes, neutrophils, moderate quantities in spleen, lymph node, and bone marrow, and at very low levels in thymus. Expressed in Ag-presenting cells (DC, monocytes, macrophages and B-cells), as well as on granulocytes. Expression was decreased in DC by signals inducing its maturation (e.g. CD40 ligand, LPS, and TNF alpha).
INDUCTION: Isoform 2 mRNA expression is up-regulated by agonists of neutrophils CSF2/GM-CSF, IL3/interleukin-3, IL4/interleukin-4 and IL13/interleukin-13.
DOMAIN: Contains 1 copy of a cytoplasmic motif that is referred to as the immunoreceptor tyrosine-based inhibitor motif (ITIM). This motif is involved in modulation of cellular responses. The phosphorylated ITIM motif can bind the SH2 domain of several SH2- containing phosphatases.
SIMILARITY: Contains 1 C-type lectin domain.

ModBase Predicted Comparative 3D Structure on Q9UMR7
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
